不可見單根三色螢光纖維：該纖維可用來製作防偽紙張。該纖維在自然光下為近白色，混入紙漿抄紙後，自然光下纖維不可見，用紫外燈照射，可見隨機分布在紙張中的纖維發出螢光，在同一根纖維上有“紅-藍-綠”等三種螢光色色段組合，用針可將纖維挑出。

定義
Invisible three-color fluorescent securityfiber: The fibers can be added in the paper pulp to making the security paper.They are colorless(white), when they are distributed in the white paper, theyare invisible under the natural light, and they can fluoresce under thelong-wave ultraviolet light. There are three different colors such as “red,green and blue” on a fiber, the three colors are arranged by the same order.The fibers can be extracted from the paper using the needle.
造紙用防偽短纖維長度1-10毫米，直徑20-100微米，具體分為三大類：（1）可見短纖維：又稱有色短纖維，自然光下可見，顏色隨意；（2）不可見短纖維：又稱隱形短纖維、螢光短纖維，紫外燈照射下發出各色螢光；（3）色譜短纖維、複合短纖維、異形短纖維、多色段DNA色譜防偽短纖維：在一根纖維上複合多種防偽功能，可根據客戶需要定製顏色組合、色段長度、纖維形狀。
用途
紙張是印刷各種包裝的物質基礎，一些採用特殊工藝製造的專用紙具有防偽特點，在專用紙張中採用的防偽技術之一就是防偽短纖維。防偽短纖維的使用方法有兩種，一是在造紙過程中將紅、藍、綠、棕色等彩色短纖維、各種螢光短纖維摻入紙漿內，二是在紙張未定型前或塗布膠水後將防偽短纖維撒在紙張表面，在自然光或紫外燈照射下即有不同效果色光或螢光反射。
Anti-counterfeit fiber(anti-forgery fiber,anti-clone fiber, authentication fiber, tracing and tracking fiber, anti-theftfiber, traceability fiber, security fiber):
The fiber's length is between 1 millimeterand 10 millimeters, it's diameter is between 20 micrometers and 100micrometers. There are three major types of the fibers: 1, Visible securityfiber (such as red, green, blue, also called visible fiber). 2, Invisiblesecurity fiber (also called colorless UV fluorescent security fiber), it canfluoresce(such as red, green, blue) under the ultraviolet light. 3, Compositefiber: There are more than one anti-counterfeit features on a fiber which canbe made by customer's order.
The paper is usually used to make thepackaging of products. Sometimes the paper of the packaging need to be addedsome anti-counterfeit features. To add the security fiber in the paper pulp isa effective method to make the anti-counterfeit paper, another method is todistribute the fiber on the surface of the paper which is covered by the glue. It is very difficult to counterfeit the packaging which is made by the paperwith security fibers.
